Amazon's Algorithm Favours Its Own Products Over Cheaper Alternatives

ProPublica found that Amazon's buy box algorithm often selects Amazon's own products or those of sellers who pay for its services, even when cheaper options exist. This results in customers paying higher prices, with an average difference of $7.88 per product. Sellers who do not pay for Amazon's Fulfilled by Amazon programme are disadvantaged and may lose sales. Amazon states that the algorithm considers factors beyond price, such as shipping speed and customer service.

Uber's Secretive 'Upfront Fares' Algorithm Cuts Driver Pay in Many Cities

Uber introduced an opaque algorithm called 'Upfront Fares' to calculate driver pay in 24 U.S. cities, replacing the previous time-and-distance-based rate. Drivers report lower and unpredictable earnings, with Uber taking a larger cut of fares. The company claims the change gives drivers more control, but critics say the secrecy makes it impossible to verify fair pay. The algorithm may learn the lowest rate drivers will accept, potentially driving down wages.

Algorithmic Pricing Glitch Causes $24 Million Book Listing on Amazon

Two booksellers on Amazon, profnath and bordeebook, used algorithmic pricing to automatically adjust their prices relative to each other. Due to a lack of upper price limits, their algorithms entered a feedback loop, driving the price of a used copy of 'The Making of a Fly' to over $23 million. The error was discovered by a researcher and the price was later manually corrected by one of the sellers. No purchase was made at the inflated price.

Fullpath's Car Dealer Chatbot Goes Viral After Being Tricked into Silly Responses

Fullpath's ChatGPT-powered chatbot for car dealers went viral after users tricked it into generating silly responses, including a $1 car price and a Tesla recommendation.

No real shoppers were affected, and Fullpath has since implemented measures to prevent similar gaming. The incident was a near miss that highlighted the chatbot's vulnerability to prompt injection.

The Attorney General of Washington DC filed a lawsuit against 14 large landlords, alleging they used RealPage's YieldStar software to form “a District-wide housing cartel” that artificially inflated rents.

This alleged scheme caused residents to pay millions of dollars above fair market prices during a housing affordability crisis.

Uber and Lyft pricing algorithms charge more in non-white areas

A study of over 100 million rides in Chicago between November 2018 and December 2019 found that Uber and Lyft's pricing algorithms charged higher fares per mile for trips to or from neighbourhoods with higher proportions of non-white residents. The researchers analysed trip data against census demographics and found no statistical link to higher demand in those areas. Both companies acknowledged the study and said they would review the findings, but no changes have been reported.

Airbnb smart-pricing algorithm increased racial revenue gap, study finds

A study by Carnegie Mellon University found that Airbnb's smart-pricing algorithm increased the revenue gap between White and Black hosts, even though it narrowed the gap among hosts who adopted it. The algorithm, which sets daily prices automatically, was adopted by fewer Black hosts, so its suggested prices were closer to the optimum for White hosts. The researchers said the tool could reduce racial disparities only if more Black hosts adopted it.
